“…In addition to chromium, these are often cobalt, nickel, copper, etc. One ton of salted skin produces about 200 kg of leather and about 600 kg of waste (Cabeza et al, 1998). With the cessation of the use of chrome tanning salts and heavy metal dyes open up other options, such as the use of waste as fertilizer in agriculture, especially in organic farming.…”

“…Moreover, non-tanned wastes are used as raw materials for glue, gelatine, technical fats, protein sheaths and even feed and fertilizers. Nevertheless, for economic reasons, waste remains mostly unutilized and goes to landfills [10]. In this regard, different researchers utilized fleshing in feed, compost, biogas, biodiesel production as well as in bioenergy recovery [11][12][13][14][15][16][17][18].…”

Reusing Limed Fleshing Wastes As A Fatliquor In Leather Processing

SULPHATED fatliquor was prepared from fats of sheep limed fleshing wastes to be used on small scale leather processing. The chemical properties of fats were determined before sulphation, thereafter they were neutralized with ammonium hydroxide to produce fatliquor. The chemical characteristics of the prepared fatliquor were then determined. The prepared fatliquor was applied onto light and heavy leather processing. Physical, chemical and organoleptic properties were determined, and scanning electron micrographs of finished leathers were obtained. The results showed that total fat content in sheep limed fleshing wastes constituted about 20% of its initial weight, of which unsaturated fats represented 60% and predominated as oleic acid. This indicates suitability of the prepared fatliquor for sheep leather processing. Additionally, the quality of finished leather processed by this technique is comparable to that obtained using a commercial fish oil-based fatliquor . These results imply that sulphated fatliquor derived from flesh waste can be reliably used in leather manufacturing as an appropriate alternative to traditional fatliquor to reduce tannery pollution and production costs.

“…The environmental effects of such proceeding go far beyond the potential contamination of the environment. The reuse of chromium from tannery waste could help save energy and financial expenditure for chromium ore output and processing (Cabeza et al, 2010).…”

An attempt was made to monitor the level of chromium from chrome buffing dust waste (CBD) from Nilest tannery through preliminary investigation of the physicochemical characteristic of dried buffing dust (CBD) waste: pH, temperature (°C), alkalinity (mg/L), ash content (%), crude fibre (%) for example, using effluent and reference water sample as (control). Comparative study of the mean values of CBD, effluent and reference water sample were also assessed. Comparative studies of fungal isolates from CBD, effluent and reference water were also assessed in situ. A total of four fungi species were observed from CBD: Aspergillus niger, Penicillium sp., Aspergillus flavus and Aspergillus fumigatus with fungal count of 5.43 × 10 3 CFU/ml, followed by effluent sample: A. niger and A. flavus with fungal count of 2.48 × 10 3 CFU/ml and none was observed in reference water sample. The study recommended the combination of pyrolysis incineration and bioremediation methods for effective treatment of chrome buffing dust (CBD).
